Product details
Overview
74LVC162245ADGG:11 from Nexperia is a 16-bit dual 8-bit bidirectional transceiver with integrated 30 Ω series termination resistors, 3-state outputs, and 5 V tolerant I/O. It operates from 1.2 V to 3.6 V supply, supports mixed-voltage translation between 3.3 V and 5 V systems, and features independent direction (1DIR/2DIR) and output enable (1OE/2OE) controls per 8-bit port. Used in high-speed bus interfacing for industrial control backplanes and memory expansion modules.
For engineers reviewing the 74LVC162245ADGG:11 datasheet, 74LVC162245ADGG:11 pinout, 74LVC162245ADGG:11 application, or 74LVC162245ADGG:11 equivalent, this device delivers verified 5 V tolerance, sub-6 ns propagation delay at 3.3 V, IOFF partial power-down protection, Schmitt-trigger inputs for noise immunity, and bus hold functionality on data pins - critical for stable operation in noisy embedded bus environments.
Technical Context
This transceiver implements two independent 8-bit bidirectional data paths, each with dedicated direction and output-enable inputs, enabling flexible configuration as either one 16-bit or two concurrent 8-bit transceivers. Its CMOS architecture supports rail-to-rail input thresholds compliant with JEDEC JESD8-7A, JESD8-5A, and JESD8-C standards across 1.2–3.6 V operation.
The integrated 30 Ω series termination resistors reduce signal reflections on PCB traces without external components, while the IOFF circuit actively disables outputs during power-down to prevent backflow current. Bus hold (on 74LVCH variant) maintains valid logic states on unused data inputs, eliminating external pull-up resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - Enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains. |
| I/O Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V buses without level shifters in mixed-voltage systems. |
| Propagation Delay (tpd) | 1.0 ns (min) to 5.7 ns (max) at VCC = 3.3 V - Supports >100 MHz bus timing with deterministic latency. |
| Integrated Termination | 30 Ω series resistors per I/O - Reduces PCB trace reflections and eliminates need for discrete termination components. |
| IOFF Protection | Active during VCC = 0 V - Prevents damaging back-current flow when powered down while system buses remain live. |
| Bus Hold Current | ±10 μA to ±75 μA (VCC-dependent) - Maintains stable logic state on floating data inputs without external biasing. |
| Operating Temperature | −40 °C to +125 °C - Qualified for extended industrial and under-hood automotive-adjacent applications. |

| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH signal selecting data flow direction (A→B or B→A) per 8-bit port. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVCH162245ADGG | Includes bus hold on all data inputs; identical pinout, timing, and electrical specs otherwise. | Eliminates need for external pull-ups on unused data lines in high-density PCB layouts. | Select when floating data inputs must be held without board-level resistors. |
| SN74LVC162245ADGGR | TSSOP48 package (same footprint), TI-manufactured; propagation delay up to 7.5 ns at 3.3 V vs. 5.7 ns for Nexperia part. | Higher timing uncertainty may limit use in >80 MHz synchronous bus designs. | Select only if TI supply chain alignment outweighs 1.8 ns timing penalty in timing-critical paths. |
Compared with 74LVCH162245ADGG, the 74LVC162245ADGG:11 trades bus hold for marginally tighter propagation delay; compared with SN74LVC162245ADGGR, it offers superior timing consistency and lower dynamic power dissipation at equivalent loads.

FAQ
Does 74LVC162245ADGG:11 support hot insertion?
Yes - its IOFF circuitry ensures outputs enter high-impedance state when VCC = 0 V, preventing back-current flow during live-board insertion. This allows safe hot-plug operation in modular backplane systems where boards may be inserted or removed while the main bus remains powered at 5 V.
Can 74LVC162245ADGG:11 operate at 1.2 V with 5 V inputs?
Yes - the device is fully specified for 1.2 V VCC operation while maintaining 5.5 V absolute maximum input voltage rating. Input clamping diodes and robust oxide design ensure no damage or latch-up occurs, and VIH/VIL thresholds scale correctly per JEDEC JESD8-7A for 1.2 V systems.
What is the impact of the integrated 30 Ω resistors on signal integrity?
The 30 Ω series termination matches typical PCB trace impedances (40–70 Ω) in source-series configuration, reducing overshoot, undershoot, and ringing by damping reflections. Measured eye diagrams show >30% improvement in jitter margin versus discrete resistor implementations at 100 Mbps.
How does bus hold differ between 74LVC162245ADGG and 74LVCH162245ADGG?
Only the 74LVCH162245ADGG variant includes bus hold on data inputs (1A0–1A7, 1B0–1B7, 2A0–2A7, 2B0–2B7); control inputs (DIR/OE) lack bus hold in both versions. The 74LVC162245ADGG has no bus hold - unused data lines require external pull-up/down resistors to avoid floating states.
